There’s already an existing and pretty long-standing suggestion to add “actor profiles”. From the looks it seems the OP is missing some of the mock-ups… but topics like showing the full filmography are discussed in the subsequent thread. I suggest you comment/vote in that thread to give it another spin – this should be preferable to a duplicate suggestion which will distract votes.
You can already see such a page on https://watch.plex.tv, searching for an actor (though this is completely untethered to your own library)
